Kenberg: Settings/system will get you your CPU etc. i5-3317 is:
- i: an i-series Intel CPU
- 5-: midrange in that generation (i3 is low-end, i7 is high-end, i9 exists, but we won't get one)
- 3: third generation (new ones are 14xxx - 14th generation. So it's at least 10 years old)
- 317: straight model number. There are codes in there, but basically: "higher is more powerful within that level and gen"
- u: specialty information. U in this case means "ultra-low-power", almost certainly laptop, very likely thin- or fanless laptop.
More detail (from 9th-gen) available
at this MakeUseOf link or I'm sure at wikipedia or other places (this is the one I found for confirmation of my knowledge).
Winston: There are lots of "intro-to-linux" and "windows look-and-feel" distributions out there, and I'd go looking for one of those to start. Helene has the basic path on how to install, but deciding *what* to install is a big thing. Ubuntu has a great install base and community, but learning any of the window managers (GNOME by default, but there are KDE and MATE (windows-like) variants) will be a curve in addition to "what is my X-equivalent". Many have suggested Linux Mint as a good "low-admin" start into Linux (and it also has a MATE flavour).
I *strongly* duplicate her
"build a live-boot USB, and use it in live mode for a while" strategy (or "I have an old computer I can sacrifice to single-boot linux" strategy). Installing dual-boot isn't trivial (although most user-friendly distros' installers make it "as easy as possible"), and you don't want to get it wrong. The first step in Linux is "learn how to do what you did in Windows", and maybe some "here's how to do simple management". The second step is "work with Linux enough to get an understanding of how we think" - which means that when you do go to "install dual-boot, repartition the drives, decide on a window manager (or install 4 or 5 and try them out), fix whatever didn't install right,..." you'll at least understand the answers given to you (or even the questions!) It isn't hard, but there is a bit of "first time playing Precision" to deal with. And doing it all from a "Okay, my brain is full, reboot and get back to what I know" or "argh, I have to do this *right now*, don't have time to learn how to do it in linux, reboot and do it the normal way" world - and a "oh, I did something strange, I don't know how to get back to what I had" (reboot into live, and everything's back to normal. In worst case, reimage the live-boot, and everything's back to normal) is just more comfortable (if slow. remember, you're running the OS off a *flash drive*).
The added benefit of "learning with a live USB" is that once you are comfortable, you can reconfigure the live USB with on-board storage, and just carry it around with you - any computer you can "boot from USB" is now "your comfortable environment".
